windows音频操作相关

[xiaoxiaokun888]

背景：PC机上有多个声音输入设备
目标：绘制多个输入设备的音轨图
问题点：1、有没有API直接获得声音振幅绘制音轨用，而不用在读取声音数据。
2、如何确定多个Mic的设备ID，底层都是0~N。可否获得硬件ID

引用 2 楼 zgl7903 的回复:

Peak Meters 使用多媒体API枚举音频设备

感谢回答，貌似都不对。 可能有10个角色，每个角色有一个Mic，都连接到同一台PC上。知道角色和设备硬件ID的映射关系，但是WAVE族API，打开音频设备ID为0~N啊

自己顶一个 就是想知道硬件Mic和ID（0~N-1）的映射关系
